    TAN 53mph...not bad for them.

    Sliding east of PVD now. 120mph for the bald eagles.

    Must suck to get meh wind, but lose power because of wind around you.

    Boire Field Emphasis on the bore.
  6. dendrite
    100kt winds there at about 1500’.
  7. dendrite
    Impressive. Still moving into SE MA.

    I got a rock.

    The drop in voltage only affects the maximum possible recordable wind speed. IIRC, the max is around 175mph at 150ft but drops to under 140mph at about 250ft. They have large and small wind cups too which have different accuracies and max capabilities at different speeds and cable lengths. Just found this... https://www.novalynx.com/manuals/WRM_apnote15.pdf Most of the Davis stations now have an integrated sensor suite or wireless anemometer transmitter so lengths are generally 40ft or less.

    It’s tough to get a near instantaneous mechanical sensor since you need to get a specific number of revolutions per given time to determine a speed. There’s just not enough rev samples if you try to cut it down to under a second. Now they could be using a 3rd party ultrasonic sensor that would have instantaneous capability, but my assumption was that they had the cups. Here’s Davis’ speed equation calculation...

    I’ll add that the Davis is NOT instantaneous. It’s actually a 2.25 second average. There’s a magnetic reed switch that measures the amount of revolutions per the given time.

    There you have it. Time to retire that one or calibrate it. lol

    http://bluehill.org/observatory/2013/01/current-conditions/ Looks like the strongest their Davis has recorded back to 2004.

    76mph on the MQE Davis.

    Later this afternoon for you guys.
  16. dendrite
    In the eye?
  17. dendrite
    BED 55mph

    Wasn't that W-SW? Are you blocked a bit to the SE? This guy has been over 50mph. https://mesowest.utah.edu/cgi-bin/droman/meso_base_dyn.cgi?stn=C0451&time=GMT

    ACY 63kt
  20. dendrite
    I don't think it ends up that big of a deal for us. LLJ max is just too far SE.
  21. dendrite
    Not sure how it compares historically to the official gear... https://mesowest.utah.edu/cgi-bin/droman/meso_base_dyn.cgi?stn=C2236&time=GMT
  22. dendrite
    50G68mph on the MQE Davis right now.

    PWATs

    35mph at TAN now.
  25. dendrite
    DXR 51mph
